Full Auto - Second Grow

[NickyChicks]

Thanks John, sure looks that way. Autos are a different animal! I'm excited for harvest tho, I bought an HerbsNOW drier and I can't wait to try it out. Really hoping it makes drying a bit more simple. I was happy with the Grove bags I bought, made curing pretty damn easy, almost foolproof in my opinion. Praying for a bountiful harvest

The grow looks great. Looks like harvesting will be spread out well.

And for me it is the opposite. Always seeing my ph go up. I chase it less these days as I too have sort of figured out how to keep it more stable.

[NickyChicks]

For now I'll keep checking twice daily. Demanding she is!

NickyChicks I just wanna say this again to try and make sure there are no misunderstandings between us. It's also important to take into consideration the differences in our water sources.

I don't think it was pH fluctuation per se that caused the leaf markings, but rather the pH being out of range for too long or too often. You know how I was saying that when I change my reservoir, after I've added nutes my pH is at 5.4, so I was taking it up to 6.2-6.3, and I'd come in and check the next morning and it would be around 5.3. So I always catch this quickly and raise the pH up to 6.4-6.5. This has never caused any problems during flowering.

On this last grow I started taking the pH in the newly mixed batch of nutes all the way to 6.5, and the next morning it would be around 5.8 or 5.9, so still within a good range. It would be all the way down the next morning, so I'd take it back up to 6.4. Then the fluctuation would slow down for the rest of the week. It's like I'll worry if there's not any fluctuation; I don't think it's good for pH to sit there all week at 6.2. I like to see it fluctuate.

Perhaps you do need to check twice daily for a while, and see if that helps. The goddess Cannabis can be demanding, but in the end she is always so generous with us.

I'm with alltatup I Chased Ph for at least one grow, found out it was more of a CalMag issue.

[NickyChicks]

Thanks Tat! That's actually exactly what I did this time, i just checked pH on all of the plants and right now they're between 6.2-6.4. I'll check again when I get home from work tonight and see where they're at. The reason I worry is because 2 weeks ago 2 of the plants had markings showing up on their leaves. It was clearly from the fluctuations and I never had issues with massive drops in pH. Hopefully, starting closer to 6.5 will help, I'm writing down all of the pH readings I take this week so I can keep track.

[alltatup]

They look excellent. Why worry about shifting pH? Just adjust it all the way up if it drops daily. When I re-do the reservoir, pH is always low the 2nd and 3rd day, so I raise it to 6.4 or 6.5. Then it stabilizes for the rest of the week, or drops slower. I guess I assumed that it's just the nature of the beast...

Day 57 (38 for NYD), despite having issues trying to understand why my pH is dropping the girls are all looking good. The Blue Cookies and the Strawberry cheesecake are starting to fill in nicely. I have a feeling the tent is going to start getting a little tight over the next few weeks.

I bought another pH meter and calibrated them both last night. They read pretty damn close to one another, not bad for inexpensive meters. The new pH meter is a pH/TDS combo pen, the TDS isn't as precise as the one I've been using but that's ok.

Day 50 for the girls and Day 31 for NY Diesel. Another water change and some defol. Starting to get some baby buds on the SC and BC, the SC is smelling nice already. I don't think I mentioned but I added my UVB t8 bulbs to the tent, they turn on for 2 hrs a day. I will increase their on time by 15mins weekly.

Three of the plants had their pH drop down to right about 5.0 when I know it should be right about 6.0. The blue cookies that's flowering, Glueberry OG, and blue dream. The Northern lights had its pH jump to almost 7.0. The NL and BD both showed signs of pH fluctuations in their leaves.
How can I better understand what is causing the pH to fluctuate? The plants that had the drop in pH are drinking water, the BC about 2gal/wk, the GO and BD about .75gal/wk. The NL drank less than half gal.

looks great. all around.

[RagWeedDWC]

I think they look awesome, nice and healthy.

Looking good to a non DWC person

Yesterday was Day 43 for the girls, Day 24 for the NY Diesel. With the exception of the NYD, every plant is now showing pistils! The Blue Cookies are drinkers, the one further along in bloom, about 2gals in a week. The NYD was topped and tied down for a quadline earlier this week. Other than that, just the normal weekly water change and I gave out a few haircuts the 4 who are just transitioning into bloom.

I like them, and your plants seem to also
